3. Key technical parameters
Successful CNC services are dependent on the precise control of the following key parameters:
Spindle speed and cutting speed: depending on the diameter of the workpiece and material characteristics, the appropriate cutting speed is determined to ensure machining efficiency and tool life.
Feed rate: the speed at which the tool or workpiece moves, which directly affects surface quality and cycle time.
Cutting depth and back eating amount: the amount of material removed by each cutting needs to balance the machining efficiency and precision of the parts, to avoid vibration or heat accumulation caused by too deep cutting.
Cutting fluid use: Choosing the right cutting or cooling fluid can reduce temperatures, minimise tool wear and improve the machined surface.
Detailed parameter selection usually relies on cutting volume manuals and test cut data.
